January 18, 2010 at 13:42 Posted in First off, we are going to take a look at the Alpine 11 Pro. This is a low wattage, small footprint (similar to stock) CPU cooler, designed to keep CPUs at a respectable temperature with limited room needed to do so. This very well may be something that you buyers are looking for in your next HTPC build. Specifications With the Alpine 11 Pro, we are given a very stock-like cooler. Overall dimensions of the Alpine 11 Pro also stay close to stock as well.
The main difference is the square versus round sides. While the Alpine 11 Pro is an Intel specific cooler, it is fitted for both LGA775 and LGA1156; just bear in mind that there is a company set 95 watt limit. Atop all the aluminum that is the main body of the cooler is the 36.7 CFM, near silent, anti-vibration fan. The fan is PWM controlled and runs at 500 RPM while at idle and up to 2000 RPM while at full load. The Alpine 11 Pro, being smaller, only weighs in at 428 grams and believe it or not, this little bugger has a six year warranty.
Test System & Test Results TweakTown uses a different method for testing CPU heatsinks which allows for an even playing field across all product tests. We feel that by using the same ambient temperature and strict lab-like testing procedures we are able to accurately compare one product to another. Keeping the test rig under 70 degrees with a cooler that is billed to only handle 2/3 of that power is quite the accomplishment, especially with a 92mm fan. With the abuse I put through this cooler I see no reason why this cooler should not perform as stated on the packaging with a Q9550 at stock speeds. I am pleased to tell you that under normal operation the Alpine 11 Pro will be near silent most of the time.
During my idle temperature run, I could see the fan spinning, but had to put my ear within a foot of it to hear it, and even then just barely. Once I cranked up the voltage to the load test the fan was more audible. Even with near full 12V going through it I was impressed with the relative silence of this 92mm fan. Conclusion Everything considered, the Alpine 11 Pro is a champ for your 95W or lesser processor. Height allowing, this is one of the perfect solutions to SFF or NTPC builds.
Not only is the Alpine 11 Pro near silent most of the time, but even under the extreme loads I subjected it to, it was still reasonable to the ears. As I said in the testing, keeping this rig at sub seventy degree temperatures with a 92mm fan keeping things under control is one thing, but doing it quietly and while only rated for 2/3 of that power is a feat in itself. Issues with the Alpine 11 Pro are really non-existent.
It is what it is, a simple budget cooler. No thrills no frills, just an easy cooler to use, that all one has to do is pull it out of the box and install it. With pre-applied MX-2 and very simple mounting hardware, I can’t find fault anywhere. Around the web the Alpine 11 Pro can be found for around $20 USD plus shipping, but is surely a smaller budget solution to cooling low wattage chips in limited space.

January 18, 2010 at 13:13 Posted in Moving ahead today though, Phenom II is one of the most versatile processors, due to its dual mode memory controller. You can easily put a Phenom II processor into any AM2+ motherboard and use it with DDR2 memory or AM3 based motherboard and run it on DDR3 memory and this is one thing AMD definitely got right. AMD’s own marketing strategy for Phenom II is for high-end market, and it leaves a gap for the mainstream segment, but not anymore we see. Dual Mode Memory AMD’s dual mode memory controller supports both a DDR2 and DDR3 Dual Channel memory controller on the single CPU. This allows for a seamless upgrade path allowing users with current AM2+ motherboards to use the Phenom II and Athlon II processors in their current motherboards with DDR2 memory, while allowing upgrade path to DDR3 at a later date.
Caches This is where Athlon II makes its distinction from the Phenom II line. Athlon II has had a cache cut done in order to save money on production as well as to reduce its overall performance. Phenom II processors come with three caches – a Level 1 cache, a Level 2 cache and a shared Level 3 cache. Athlon II has no Level 3 cache integrated to the System Command Queue or better known as the integrated Northbridge. The L2 and L1 cache sizes are identical to the Phenom II processors, so no changes have been made there. Looking at the Athlon II processor there isn’t much different at all apart from the writing on the top of the IHS.
